Applicationfiled May 23, 1927. Serial No. 193,492. 1

tion'is the provision of means to assemble a rubber heel with its heelbase, before said heel and base are delivered to the shoe heeler. Inother words, instead of the shoe heeler handling three units, viz., theshoe, heel base, and rubber heel, I reduce the number of units to two,viz., the-shoe, and the completely assembled and prepared heel base andrubber heel, firmly united as a single unit;

Incarrying out my present invention, I preferably utilize a machineasillustrated in the present-application, which machine I believe to benovel, and have therefore claimed broadly herein.

By the use of my novel machine I attach the heel base and the rubberheel, firmly uniting same and preparing both as a unit for simultaneousattachment to the heel portion of the shoe instead of, as formerly,

necessitating separate and successive attachments, first of the heelbase, and then of the rubber heel. assembling the heel By my inventionof thus first base and rubber heel into a single unit, the same can thusbe simultaneously attached, the completed heel base and rubber heelbeing handled as a single article and at a single operation.Furthermore, it is a much easier and simpler proposition to aline,assemble and unite .the' heel base and rubber heel while each areseparate,

rather than after one of the same is attached to the shoe. Also, intheir thus assembled relation,- the bufiin'g, trimmingor finishing ofthe'heel breast and sides and rear of the heel'is greatly simplified,without requiring the. time, delay, skill, and machinery necessary tohandle the completed shoe and heel in the heel breast scouring actionfFurther details of construction, advantages, combinations of parts, willbe hereinafter more fully 'claimed.

is not essential, as I' may'vary such number I without departing fromthe spirit of the invention. Y

As shown novel clamping 7 device comprlses a plate or table 15, securedto the cross shafts" 8' by vided on thetable :15, having Ja'fac'e 18 indetail in Figs.-4 and 5, my

against which the rubber heel 19, illustrated;

One endo'l the lei-er isprovided v vl h a recess 71 in which fits .a hip; I2 'hichis a psior aslide 3, said slide 73 having a slotadaptcd to slide over a scre v orthe lilge 7 5. The llllpel end 76 of the slide 73 enters a slot in. theplate 15, and on upward 'ii' ovement of the lever 66, the slide T3 isalso raised, thus projecting the y then lirn ly imited rubber heel andheel base from the clamping device and into a hopper or vthe lilge 77,provided therefor. It will be appreciated that at the time of thisdischarge of the completed unit the roller 53 of the clamping deviceunder discussion will have contacted with the stationary cam 54, andwill have ridden up on said cam a suiticient distance to allow theplunger 51 ,to be opened or spaced from the united heel and a 9 Perm h dscharg f e r be lieel and base from their guides and the plate 15. Itwill also be apparent from a glance at the drawings that the rods 48pass through the reinforcing portion 62 as 'well as through the plate15. The same arrangement of levers 65 and 66 is provided for each of theclampinginst'ruinentalities.

The springs 55 between each opposite pair of clamping devices are soinounted that they will not interfere with each other throughout theirextent across the interior of the machine, the brackets 57 on eachclamping device being angled or positioned to insure clearance betweenthe various sets of springs.

It will thus be appreciated that I have devised an eatremelyefiicient,quick acting, and positive machine for the purpose set forth, greatlyincreasing the speed of shoe manufacture by reason of the reduction inthe "number of operations heretofore 'required by the shoe-heeler. hlyprese nt machine is siinple in operation, and will be readily understoodby those skilled inlthe art, the operation'of same being as follows:The. operator having a plurality of rubber heels and heel bases, eithercoats one or both of the contacting surfaces of said heels and bases andpreliminarily unites the same, or has the thus-united heels and basesdelivered to him in this condition, depressesthe .fo'ot treadle 13,shifting the driving belt ll to the pulle s. and setting the machineoper t n- There pqi each su ess ve laiaPJQQdeYiQ' tea hes e to]? of heinichi faccesj ible to the operator, the operat or positions a cementedheel and base in t e" guides therefor, the plunger 5l'beinig raised bytlie'cairi-fifi, the. clamping device passi to ,the'right, viewedin'Fi'g. 1,
